Abstract

Torque in a shaft is detected by means of non-contacting sensors sensing a torque-dependent magnetic field emanated by an integral transducer region of the shaft that is circumferentially or longitudinally magnetized. The shaft is driven by a motor and subject to a longitudinal magnetic field which acts on interference field. In one implementation of the invention coils are energized to provide a counteracting magnetic field to compensate the interference field.
